Exercise is medicine! Although this premise is well established, how to maintain this “treatment” for various diseases during the COVID-19 pandemic? This has been a concern of all doctors in the world since exercise contributes to the control of cardiovascular diseases and other comorbidities recognized as risk factors for a worse outcome in COVID-19. Moreover, it has already been shown that higher cardiorespiratory fitness is inversely associated with the likelihood of hospitalization due to COVID-19. In addition to the hygiene […]

The disease caused by Coronavirus 2019 (COVID-19) is associated with significant mortality and morbidity, including pulmonary and cardiac adverse sequelae.1–3 It began in December 2019 in the city of Wuhan, and quickly became a pandemic, declared by the World Health Organization (WHO) on March 11 of 2019.4 By early September 2020, more than 28 million patients have been confirmed infected by COVID-19 in more than 200 countries.3 […]

Why we must exercise? Although this question has many answers, many other questions arise from it. Which are the benefits of exercising? How much exercise is good for health? Is high-intensity exercise better than moderate-intensity exercise? Are there risks in exercising? What to do if someone does not like to exercise? Do cardiologists know the literature on exercise and heart? These are sounding questions that should be covered to understand the real need of exercising. […]

Abstract Despite the health benefits of routine exercise, coronary artery disease (CAD) is common among older competitive athletes and is an important cause of sudden cardiac death. Athletes with suspected or confirmed CAD routinely undergo conventional coronary angiography involving the performance of invasive coronary physiological assessment using the fractional flow reserve (FFR) or the instantaneous-wave free ratio (iFR). Data defining the role of invasive coronary physiological assessment, while robust in general clinical populations, are untested among older competitive athletes with […]

Introduction Sudden cardiac death (SCD) related to sports activities is an unexpected and rare event, usually occurring in young and apparently healthy athletes. The main cause of SCD in young athletes (< 35 years old) is ventricular arrhythmia (VA) associated with arrhythmogenic disorders (e.g. hypertrophic cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy - ARVC, channelopathies). Some of these conditions can be suspected by routine pre-participation clinical evaluation, while others remain undetectable even after careful screening.– This paper presents the case of a [...]

A aptidão cardiorrespiratória (ACR) é considerada padrão-ouro para avaliação do desempenho aeróbico de atletas e da população normal, tendo sido recentemente denominada sinal vital clínico e indicador essencial de função cardiovascular e pulmonar. A ACR está associada a menor risco de eventos cardiovasculares fatais e não fatais, tendo estudos demonstrado sua associação consistente e inversa com mortalidade, mesmo após ajuste para fatores de risco tradicionais. Além disso, tanto o consumo de oxigênio máximo (VO2max) quanto o consumo de oxigênio (VO2) […]

Resumo Fundamento: A remodelagem cardíaca depende da intensidade, da duração e do método de treinamento. Objetivo: Avaliar se o treinamento realizado em uma tropa especial portuguesa incrementa a remodelagem cardíaca em uma amostra de jovens que previamente praticavam esporte de competição. Métodos: Estudo prospectivo que incluiu 76 militares candidatos a tropas especiais, 45 dos quais praticavam previamente exercício físico de nível competitivo (> 10 horas por semana). Destes militares atletas, apenas 17 concluíram com sucesso o curso. A avaliação foi […]

Introdução A síndrome de Marfan (SMF) é uma doença autossômica dominante hereditária, causada principalmente por mutações no gene fibrilina-1 (FBN1). Caracteriza-se pela presença de aneurisma e/ou dissecção da aorta torácica, subluxação do cristalino e anormalidades sistêmicas. O maior risco de óbito na síndrome é atribuído às patologias cardiovasculares, em especial o aneurisma progressivo da raiz aórtica, levando à dissecção e ruptura se não tratado cirurgicamente. O diagnóstico clínico da SMF pode ser estabelecido pela nosologia Ghent revisada, mas isto pode […]
